It is important that firefighters know how to use the techniques and equipment to facilitate the rescue. OBJECTIVE (SPO): The student will demonstrate a basic understanding of removing packaged victims using ladders and mechanical advantage systems through participation in class discussion and practical activities. OVERVIEW: Victim Removal * Ladder Rescue Systems * Vertical Lowering Techniques * Overland Victim Removal * Practical Activity

2 VICTIM REMOVAL SPO: EO 1-1 EO 1-2 EO 1-3 EO 1-4 The student will demonstrate a basic understanding of removing packaged victims using ladders and mechanical advantage systems through participation in class discussion and practical activities.. Demonstrate a knowledge of ladder systems used in rescue to raise or lower victims. Demonstrate a knowledge of vertical lowering techniques used to remove victims from above or below ground. Demonstrate a knowledge of the techniques used to raise and lower a victim overland. Demonstrate an understanding of victim removal systems by constructing ladder raising and lowering systems and moving a victim overland. 2

3 NOTE: Instructor should review each skill with students who will have an opportunity to demonstrate proficiency during the practical portion of the session. The instructor may also need to review basic knots used in rescue, mechanical advantage systems, and ladder lifts, carries, and raises. I. LADDER RESCUE SYSTEMS (1-1) A. Ladder Gin 1. Lay the ladder on the ground 2. Select the two ropes to be used for support and guy lines 3. Form a figure eight on a bight in the middle of each rope 4. Attach a knot to each beam at the tip by going under the top rung and over the tip (one end of the rope on each side is used for hoisting/support and the other is used as a guy line) 5. Place the ladder heel on the rear step of the pumper using cribbing to protect the step 6. Attach a sling around the beams of the ladder with the ends passing over a rung, connect the two bights together with a carabiner, placed the rope through the opening in the pulley, and attach the pulley to the carabiner 7. Stretch the support lines out and raise the ladder to about 90 degrees 8. Secure the support lines to steamer connections on the pump 9. Secure the guy lines to the railings on the rear of the pumper 10. Form a loop in a piece of webbing and place it around one of the tow hooks on the back of the pumper 11. Place the lifting rope through a pulley and attach it to the webbing around the tow hook using a carabiner (change of direction pulley) 12. Test strength of system by pulling on the rope and observing angle of ladder which should not be below 75 degrees 13. Construct a mechanical advantage system to lift the load 14. Check all knots and carabiners to make sure they are secured B. Ladder Sheerlegs 1. Lay the two ladders to be used side by side with tips even (or as even as possible) 2. Select the two ropes to be used for guy lines 3. Form figure eight on a bight in middle of each rope 4. Attach a knot to each beam at the tip by going under the top rung and over the beams of both ladders 5. Stretch out the guy lines to determined the location of pickets (two on each side) which are angled off to the tip of ladder and approximately the distance of the used length of the ladder and driven into ground 2/3 of length and 90-degree angle of the lines 6. Attach a sling to tip of ladder using both sets of beams by going around the beams with the ends dropping between the two sets of rungs 3

4 7. Connect two bights with a carabiner 8. Place the lifting rope through a pulley and attach it to the carabiner 9. Heal the ladder and raise it 10. Secure the heels of the ladder with pickets and rope (two for each side) 11. Test the strength of the system by pulling on the rope and observing the angle of the ladders (if it drops below 70 degrees, there is a possibility that the sheerlegs will collapse under a load) 12. Using webbing formed in a loop, attach a carabiner to the bottom rung on one side of the ladder 13. Pass the rope through a pulley and attach it to the carabiner (change of direction pulley) 14. Construct a mechanical advantage system to lift the load 15. Check all knots, pickets, slings, and carabiners to make sure they are secure C. Aerial Ladder 1. Can be used as an elevated anchor point or lowering device 2. Victim can be carried or sled down ladder D. Elevated Platform 1. Can be used as an elevated anchor point 2. Victim can be carried in basket II. VERTICAL LOWERING TECHNIQUES (1-2) NOTE: For any patient movement that involves above or below ground operations, plastic stokes baskets should not be used. Eye protection as well as other necessary protective measure should be taken for the victim. A. Ladder Systems 1. Ladder slide a. Raise ladder with no more than one rung above window or roof edge and secure at tip if possible b. Prepare basket, SKED, or reeves sleeve for vertical lowering c. Connect lowering line to a mechanical advantage system or descent control device if needed d. Place a second rescuer on the ladder to receive the victim e. Place the basket, SKED, or reeves sleeve on the ladder f. Lower the victim slowly watching to make sure that the packing device does not get caught on the ladder rungs g. If an aerial ladder is used, short poles can be placed on the ladder rails and the basket allowed to slide on them 4

5 2. Ladder gin a. Construct a ladder gin as described previously b. Prepare the basket, SKED, or reeves sleeve for horizontal lowering c. Attach a mechanical advantage system d. Raise or lower the victim slowly e. Once the victim is at ground level, pull the packaging device to one side as the rope system is being lowered 3. Ladder sheerlegs a. Construct ladder sheerlegs as described previously b. Prepare the basket, SKED, or reeves sleeve for horizontal lowering c. Attach a mechanical advantage system d. Lower victim slowly e. Once the victim is out of the opening, pull the packaging device to one side as the rope system is being lowered 4. Aerial device fixed anchor point a. Attach a sling or piece of webbing in a loop to the ladder by going around the beams with ends passing over a rung b. Connect the two bights using a carabiner c. Pass the rope through a pulley and attach the pulley to the carabiner d. Attach a sling or piece of webbing in a loop to a rung near the bottom of the ladder on the underside e. Pass the rope through a pulley and connect the pulley to the sling/loop (change of direction pulley) f. Construct a mechanical advantage system 5. Aerial ladder moveable anchor a. Place a hose or rope roller over tip of ladder and secure it b. Pass the rope over the roller and down the ladder to the turntable c. Attach a piece of webbing in a loop or a sling to the bottom rung d. Attach a carabiner to the webbing e. Pass the rope through a figure eight and connect the figure eight to the carabiner (this allows the rope to be adjusted easily) f. Remove all slack from the rope g. Extend and retract the ladder as needed to raise or lower the victim h. Rotate the turntable as needed 6. Elevated/articulated platform 5

9 REVIEW: Victim Removal * Ladder Rescue Systems * Vertical Lowering Techniques * Overland Victim Removal * Practical Activity REMOTIVATION: While these techniques are not used on a regular basis, they may be needed for rescue from a confined space, removal of an injured victim from a roof, or during a silo rescue. Regular practice will improve proficiency when called upon to used the skills.
